Review on ZOHAN 033 Bluetooth AM/FM Radio Headphones With 2000MAh Rechargeable Battery And 25DB NRR Noise Reduction Earmuffs For Enhanced Safety by Jim Plump

I bought these to wear on my lawn tractor for hearing protection. I wanted a Bluetooth connection for listening to music. My ears had some pressure after due to the tight fit but I get this with every ear protection headphone, so I'll blame that on my ears/head.After about 6 hours of use I decided to charge them. I came to find that my set was missing the charging cable. This is apparently a 3.5mm to USB a cable. I emailed the company and they said they didn't stock extra cables. Instead they agreed to refund me the cost of a cable. I found one here with good reviews. The rep from the company sent a photo of the cable. I also read reviews and questions here to make sure I got one with the right number of connections.I got the cable and plugged it into the headphone with a click. I then plugged it into a 500mA USB charger. Initially I got a battery icon with a charge symbol. About 30 minutes later I came back to see that symbol gone. That seemed too fast so then I unplugged them and tried to turn them on. They did not power up. I then noticed a burning electronics smell from the battery door. I instantly pulled the battery because I didn't want it to blow. Turns out the batter seemed fine. The burning smell was clearly inside of the headphone.I plan to reach out to the company and will update the review after. I just wanted to post my concerns here that the company apparently doesn't have spare parts and charging following the directions led to something breaking. If lithium battery device cannot charge properly, it's a huge safety concern.
